Urban Pollution

Causes:
Pipe Dumping
Runoff water from buildings, streets and sidewalks carries many pollutants including: sediment, nutrients, bacteria, oil, metals, chemicals, road salt, pet droppings and litter. Cars, refineries, power plants and other contaminant emitting sources send pollutants into the air that eventually settle in water. Some businesses and industries don't dispose of waste properly and dump pollutants directly into waterways. Also, when cities are built, the natural watershed is changed. Wetlands are often filled in with dirt and concrete and natural streams are redirected by man-made channels. This takes away nature's ability to filter out contaminants before they end up in larger bodies of water.
Effects:
Nasty Drinking Water
Contaminated runoff kills aquatic life. Metals and other toxins are absorbed in the flesh of fish and shellfish and are dangerous when eaten. Bacteria, parasites and chemical toxins contaminate recreation areas and drinking water, which cause major illness and sometimes death. Most streams, lakes and coastal waters surrounding large cities are too polluted for people to use. If development of cities continue without care and management of pollution and the natural watershed, most or all fish and aquatic life will be killed, entire ecosystems will be destroyed and it will be nearly impossible to find uncontaminated water that is safe to use or drink.

Dog Droppings

  • Keep roadways and walkways swept and clear of soil, grass and debris.


  • Get involved in neighborhood cleanups.
  • Go here to see activities you can do.

  • Write or call your elected representative and urge them to write legislation that protects natural watersheds from development and to develop plans for managing and controlling runoff and pollution.


  • Recycle oil, antifreeze, batteries, fertilizer, pesticides and other chemicals and materials as much as possible.


  • Businesses should follow Best Management Practices for controlling pollution, runoff and waste disposal.


  • Limit the use of your car and maintain it for leaks.


  • When cleaning your car, use a commercial car wash.
  • Click here to learn Best Management Practices when washing your car, streets, parking and sidewalks.

  • Clean up after pets and dispose of droppings in the trash or toilet.


  • Never dump anything into the ground or street and don't allow anything other than rain water to flow into storm drains
